(54) A METHOD FOR CALCULATING THE PULSE FIRING PATTERN FOR A TRANSFORMER OF AN ELECTROSTATIC PRECIPITATOR AND ELECTROSTATIC PRECIPITATOR


(57) The method for calculating the pulse firing pattern for a transformer of an electrostatic precipitator (9), the method comprising a) defining a target parameter indicative of the power to be supplied to collecting electrodes and discharge electrodes (19) of the electrostatic precipitator (9), b) calculating a first parameter indicative of the power supplied to the collecting electrodes and discharge electrodes (19) using the pulse firing pattern being calculated, in case one additional pulse is fired, c) calculating a second parameter indicative of the power supplied to the collecting electrodes and discharge electrodes (19) using the pulse firing pattern being calculated, in case two additional successive pulses are not fired, d) selecting at least one pattern element on the basis of the first parameter or second parameter, e) repeating steps b), c), d), e).
